However disaster struck Clout when he made a mistake in the final straight before the finish, going down and dropping significant positions, allowing Wilson to move in to the race lead, with Crawford following closely behind.
With Clout well and truly at the rear of the pack, the coast was clear for JCR‰Ûªs Wilson to wrap up his 2015 championship campaign with another race win to his name.
When the chequered flag flew, Wilson celebrated across the line, taking the race two win ahead of Crawford and GYTR‰Ûªs Beaton, ad wrapping up his first ever Motul MX2 championship win.
"This feels unbelievable, we have worked so hard to get this win, and a lot of people didn't believe in me at the end of last year," he said. "I have had Josh Coppins, my family, Mike Ward, Ray Howard and the top guys at Yamaha in my corner this year - they believed in me when no one else did.
"It has been a tough year, with my brother having that big crash at the start of the season, and honestly I was shattered, so to get this done for him too is pretty special.
"We've worked so hard, and to see it all pay off today is an absolute dream come true."
